Covid – 19 transmission and how to prevent it

 

Covid – 19 transmission and how to prevent it.

 

Firstly, what is Corona Virus?

The corona virus is a group of related RNA viruses that causes disease in mammals and birds. In humans, the virus causes respiratory tract infections that range from gentle to deadly. Mild illness involves some cases of common cold, while more fatal varieties can cause SARS, MERS and COVID-19. The symptoms in other species changes; in chickens, the virus cases upper respiratory tract diseases. In pigs and cows, the virus causes diarrhea. As of now, there are yet no vaccines or antiviral drugs to treat or prevent the coronavirus in humans.

Infected carriers shed the virus to the environment. The interactions of the corona virus, spike protein with its corresponding cell receptor is intermediate in deciding the tissue tropism, infectivity and species scope of the delivered virus. The corona virus, fundamentally targets the epithelial cells. They are sent starting with one host then onto the next host, contingent upon the corona virus species, by either an aerosol, fomite, or faecal- oral route. The human corona viruses contaminate the epithelial cells of the respiratory lot, while animal corona viruses by and largely infect the epithelial cells of the stomach related tract. SARS coronavirus, for an instance, contaminates by means of vaporised route, the human epithelial cells of the lungs by binding to the angiotensin-converting enzyme 2(ACE2) receptor.

Infections caused in humans

Coronaviruses fluctuate essentially in chance factor. Some can kill over 30% of those infected. Coronaviruses can cause colds with significant side effects, for example, fever, and a sensitive throat from swollen adenoids. Coronaviruses can cause pneumonia and bronchitis. The human corona virus found in 2003, SARS – CoV, which causes extreme intense respiratory condition (SARS), has an exceptional pathogenesis since it causes both upper and lower respiratory parcel infections.

 

The four human coronaviruses that produces generally mild symptoms:

1.      Human coronavirus OC43 (HCoV-OC43), β-CoV

2.      Human coronavirus HKU1 (HCoV-HKU1), β-CoV

3.      Human coronavirus 229E (HCoV-229E), α-CoV

4.      Human coronavirus NL63 (HCoV-NL63), α-CoV

 

The Three human coronaviruses that produces severe symptoms:

1.      Middle East respiratory condition related coronavirus (MERS-CoV), β-CoV

2.      Severe intense respiratory disorder coronavirus (SARS-CoV), β-CoV

3.      Severe intense respiratory disorder coronavirus (SARS-CoV), β-CoV

Common Cold

The human coronaviruses HCoV-OC43, HCoV-HKU1, HCoV-229E, and HCoV-NL63 ceaselessly circulating the human population and produce the general mild symptoms of the common cold in grownups and kids worldwide.

 

Severe intense respiratory disorder (SARS)

SARS coronavirus (SARS - CoV) was the initial name given to the infection. In excess of 8,000 individuals were infected, around 10% of whom died.

 

Middle East respiratory condition (MERS)

As of December 2019, 2,468 cases of MERS-CoV pollution had been certified by research facility tests, 851 of which were deadly, a passing pace of generally 34.5%.

 

Coronavirus Disease 2019(COVID - 19)

On December 2019, a pneumonia outbreak was reported in Wuhan, China.  The flare-up on 31 December 2019, was followed to a novel strain of coronavirus, which was given the between time name 2019-nCoV by the World Health Organization (WHO), later renamed by the International Committee on Taxonomy of Viruses as 'SARS-CoV-2'. Starting at 8 August 2020, there have been at the minimum 718,530 affirmed passing and in excess of 19,266,406 affirmed cases in the COVID-19 pandemic. Since there’s a 96% similarity to the bat coronavirus, it is suspected to be originated from the bats. The pandemic, brought in travel restrictions and lock-downs nationally throughout the world.

 

Treatments

There are no immunizations or antiviral medications to prevent or treat human coronavirus contamination. Treatment is only supportive. Various antiviral targets have been recognized, for example, viral proteases, polymerases, and entry proteins. Medications are being developed which focus on these proteins and the various steps of viral replication. Various vaccines utilizing various methods are likewise a work in progress for various human coronaviruses. But however, if you’re experiencing a cold with no symptoms of the coronavirus, you could order medicines online at 3MEDS which is the best online pharmacy .

 

 

The ways to fight the transmission while at home:

1.      Regularly and meticulously clean your hands with an alcohol-based hand wash or wash them with soap and water. (This is to kill viruses that may be on your hands.)

2.      Keep a minimum 3 feet distance between yourself and others. (When a person coughs or sneezes or speaks, there are chances of them spraying small fluids droplets from their mouth or nose which may contain the virus. If you’re too close to them, you might inhale the droplets which may be the covid-19 virus)

3.      Avoid touching your face (your hands might be contaminated by picking up viruses by touching random surfaces. So, your hands might transfer the virus to your eyes, nose or mouth and through these you could be infected.)

4.      Stay physically fit (increases your immunity)

5.      Eat a healthy diet.

6.      Avoid going to crowded places (Because it’s difficult to maintain Social Distancing)

7.      Make it definite that you and the people around you follow proper hygiene. Which means covering your mouths and noses with your elbow or a tissue. Once the tissue is been put away remember to wash your hands thoroughly (the droplets spread and the virus keeps spreading. To stop the virus from passing on to others around you.)

8.      Self-isolate yourself at home if you have the minor symptoms which is cough, headache or mild fever until you recover perfectly fine. Do not go out. Make someone give you the basic supplies. If you have to leave your house, do wear a mask (to avoid the spread of the virus onto others)

9.      If you have a fever, dry hack and trouble in breathing, look for medical assistance through a call ahead of time if it's probable and follow the headings of your nearby medical authority. (Since this will permit your human services supplier to guide you to the right health center. This additionally ensures you and furthermore forestalls the spread of the infection and different contamination.)

10.   Be in the know regarding the most recent data from confided in sources, similar to WHO or your nearby and national well being specialists.
